Tick (Doom 3)

The tick is a small, spider-like enemy in Doom 3 that has similar attack patterns to the trite. The only noteworthy differences between ticks and trites are aesthetic ones (although the tick can jump slightly farther than the trite). While trites resemble an inverted lost soul with legs, ticks appear more insect-like. What's more, while the trite makes a deep, throaty roar, the tick makes high-pitched chirps. Finally, while trites curl up and burst into yellowish-green "spider juice" upon death, tick corpses burn away like all other demons. If closely examined, a little human face can be seen on its head.

Tactical analysis
The tick cannot attack while the player is on a significantly higher vertical plane. For example, if a tick is on the floor, it can be rendered harmless by jumping onto a bunk bed.

The pistol is perfectly adequate for dealing with ticks, requiring only two shots to kill them. The machine gun is also a good choice. In Resurrection of Evil they can be killed instantly with the grabber, although it is not recommended to use it when facing a large swarm due to the slow rate of fire caused by the weapon's cool down.
